Abstract

Abstract

In this paper, a mathematical model was set up, taking the Fushun West Open-pit mine as the research area, using the GMS (groundwater modeling system) numerical simulation software, based on the analysis of the mining area and its surrounding area, geological and hydrogeological conditions, as well as the characteristics of the formation lithology and geological structure. Based on the geological exploration data of the working area and the analysis of water filling factors, a hydrogeological model was established to predict the water inflow, and the layout scheme of drainage well in equilibrium state was put forward. The results showed that according to the topographic characteristics of the mine, when five horizontal wells with depth of 100 m, length of 100 m and displacement volume of 10~20 m³/d were placed on the north and south sides of the mine, and four shafts with depth of 70~100 m and displacement volume of 20 m³/d were placed at the bottom of the mine according to the spacing of 100 m in the simulation area, no water would overflow from the mine.
